7KBRLL[1] is a very small (7 Kilobytes) roguelike-like. It is a computer game for Windows that combines simple text-based and roguelike elements. In the game, users play as subject 7KBRLL who is trapped in a room with no means of escape. Subject 7KBRLL has been injected with a substance which induces psychotic behaviors. Users employ the WASD keys to walk around the padded room (appears as an '@' in a very small roguelike room).
